Abstract (en)
Embodiments of the present disclosure provide a display substrate and a manufacturing method therefor, a display panel, and a display device. The display substrate comprises a light-emitting structure layer provided on a base; the light-emitting structure layer comprises an anode layer, a first film layer group, and a second film layer group that are sequentially stacked; the anode layer comprises one or more anodes; the first film layer group comprises at least one film layer located between an anode and a cathode in an OLED device; the second film layer group comprises a cathode, and at least one film layer located between the anode and the cathode in the OLED device; the orthographic projection of the second film layer group on the base comprises the orthographic projection of the first film layer group on the base, an overlapping portion of all film layers in the first film layer group serves as a first portion of the first film layer group, an orthographic projection region of the portion of a first portion of the first film layer group, which covers an anode surface and directly contacts the anode surface, on the base is a light-emitting region of the display substrate, and a distance between the edge of the first film layer group and the edge of the second film layer group is different at a plurality of positions.
